Original application filed August 14, 1913, Serial No. 784,672. Divided and this application led March 9,

To all whom t may concern:

Be it known that I, JOSEPH KENNEDY, a citizen of the United States of America, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Wall-Sockets, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to wall sockets or plugs such as are inserted in walls, floors or other structures of material which will not readily receive and hold the threads of a bolt, for the purpose of forming anchorage members for bolts or the like, and its object is to provide a simple device which will be securely held in a hole into which it is driven.

Illhis and other objects and advantages of my invention will appear in the following specification, in which the invention will be described and its novel features will be set forth in appended claims.

Referring to the drawings:

v Figure 1 is a transverse section of a wall with a hole drilled therein with a bolt screwed into one of my novel wall sockets within the hole.

Figs. 2 and 3 are respectively a longitudinal section and an end elevation of the socket shown in Fig. 1.

Figs. 4 and 5 are end elevations of slightly modified sockets which also embody iny invention.

Referring to Figs. 1, 2 and 3, the bolt anchor here shown comprises a hard metal shell 10 which is internally threaded as shown at 11, and is covered with a soft metal sleeve 1Q. These parts are so constructed that there are left between them at one end longitudinally tapered pockets 13 into which wedges v14 may be driven as shown in Fig. 1 to force the outer sleeve against the surface of the hole 15.

This hole is provided in a wall 16 of concrete for example, and is slightly deeper than the length of the socket and of a diameter to make a driving fit for the socket. Illhe wedges are driven into the pockets after the socket is in place.

Serial No. 13,168.

As shown in Fig. 3, both the hard metal shell and the soft metal outer covering are correspondingly grooved to produce the pockets 13 but only the outer covering may be provided with grooves 18 as shown in Fig. 4 or, if desired, the pockets may be formed in the inner member only as shown at 19 in Fig. 5. In each case, however, the pockets are located between the shell and the cover and are adapted to force the outer covering of soft metal against the inner surface of the hole, thereby preventing the removal of the anchor. A. bolt 20 or other screw-threaded member may be screwed into the socket.

This application is a divisional of that filed by me August 14, 1913, Serial No. 784,- 672 and assigned to The Clements Co. a corporation of New York.

What I claim is:

1. A wall socket comprising a hollow cylindrical shell of hard metal, means therein for receiving the threads of a bolt, an outer sleeve of soft metal upon said shell, and a liat sided tapered pocket at one end of the socket adapted to receive a wedge adapted to be driven into said pocket to displace the metal of said sleeve, said socket being formed between the shell and the sleeve.

2. A wall socket comprising a hollow cylindrical shell of hard metal, means therein for receiving the threads' of a bolt, and an outer sleeve of soft metal upon said shell, said shell being provided at one end with a plurality of equally spaced longitudinally disposed flat sided tapered grooves covered by said sleeve and adapted with said sleeve to form pockets, each adapted to receive a wedge, adapted to be driven into said pockets to displace the metal of said sleeve.

In testimony whereof I have hereunto set my hand this 3rd day of March 1915, in the presence of two subscribing witnesses.

JOSEPH KENNEDY.

Witnesses:

I. B. Moolen, E. Gr. Scnonmc.
